RESTLESS GENITAL SYNDROME: A RARE CASE SERIES OF FOUR PATIENTS AND A LITERATURE REVIEW



Fragile watermarking technique for detecting image

Aiming at the problem of image tampering and forensic localization,a fragile watermarking algorithm based on chaos sequence and image QR decomposition was proposed to determine the image tampering.The algorithm chooses QR decomposition to decompose the image,embeds Optics the watermark after the image is decomposed,and encrypts the watermark by cha
